Derivation rule formula of composite function
y=f(t)，t=g(x)，dy/dx=f'(t)*g'(x)
Derivation formula for determining parameter equation function
x=f(t)，y=g(t)，dy/dx=g'(t)/f'(t)
Not all functions have derivatives, and a function does not necessarily have derivatives at all points. If the derivative of a function exists at a certain point, it is said to be derivative at this point, otherwise it is called non-derivative. However, the differentiable function must be continuous; Discontinuous functions must be non-differentiable.
